C&H Precision FNX-45Optics Ready Slide Steel Plate For Holosun 509T FNX45-509T-ST

The C & H Precision FNX-45 Optics Ready Slide Steel Plate for Holosun 509T is a heavy-duty, unmagnified 1x optics adapter block engineered to survive the heavy recoil of large-caliber tactical handguns. Precision-machined from robust, mild-grade tool steel at their Coastal Georgia production facility, this low-profile plate features a protective black electroplated finish to resist environmental corrosion and match the slide's finish. It fits directly into the factory slide pocket of the optics-ready FNX-45 Tactical pistol, converting its proprietary factory dimensions into a rock-solid clamping bar surface optimized exclusively for the enclosed Holosun 509T red dot sight footprint. Operating entirely without internal electronics or battery power, this American-made hardware solution completely avoids the potential warping or thread stripping of traditional aluminum plates under heavy cyclic slide forces. The package comes pre-bundled with premium stainless steel plate-mounting hardware and features full coverage under the signature C & H Precision Lifetime Warranty.
